To detemine the effect of the coating to reduce heat compared to white and dark paint.
Product: ACS CIC 4.0
Goal:Reduce Solar Heat Load
Trader Johns is a fruit stand located in a 2,100 square foot corrugated metal-skinned storage shed near Wenatchee in Eastern Washington State. The building has a main area that is open on one side and a cold room located in the back. Ceramic Insulation Coating was applied to several different areas of this fruit stand to document the heat reduction achieved.
Surface temperatures were measured to show differences between ACS CIC 4.0 and standard (white & dark) paint over this metal skinned, wood framed building.
Two sections of the building were coated with ACS CIC 4.0 applied at a thickness of 20mils (0.020” or 0.5mm) on a roof section over the top of a 24’x16’ cold room and also at 40mils (0.040” or 1mm) on the exterior of the sliding door that opens into the main room of the shed. The main room of the shed maintains the ambient 84F and the cold room is just above 42F.
The data collected demonstrated that ACS CIC 4.0 was superior white and dark paint and the uncoated surfaces.
This photo shows the insulated roof sections at upper left over the cold storage room and insulated door at the right hand side of the frame. The photo shows insulated surfaces on the roof at 76F over the 42F cool room area and at 84F on the insulated door, which represents the ambient temperature. Both insulation coated surfaces’ temperatures show they’re not being radiated and absorbing heat from the sun. Nearby readings on the white painted surface show 90.2F and 93.9F with the red-coated surfaces at 106F to 106.5.
This also demonstrates that white paint absorbs infrared-based heat energy while insulation coating does not. The red painted surfaces, being darker, show their ability to absorb higher volume of infrared energy than the white surfaces.
The following photos show the effect of CIC Heat Block applications to the roof. The insulation coated roof section temperature at 76.3F shows that surface is maintaining the cold room’s cooler interior temperature (42F) more effectively. Based on the principal that heat travels towards cold, this shows the ceiling/roof envelope temperature is cooler at the surface and even less than the ambient temperature. Where surface temperatures are over the 84F ambient level, this means metal walls or roofing is absorbing additional heat energy and transferring that additional heat into the building’s interior.
